Gill's a good and effective communicator; she talks in layman's terms, which we really appreciate. In our experience, this is a rare talent in the technical world. We enjoyed working with Gill, found her input valuable and are happy to report that she 100% met our expectations.
Financial Controller, Not-for-Profit Organisation

Gill is the one person that you want on your side when you are establishing a CRM. And if you haven’t engaged her in the first instance, Gill is the one person to engage if you need your CRM to function as you had initially hoped.
Paul Gabrielides, Principal Consultant, Independent Communications Consultants

Gill "Walks on Water" when it comes to CRM and I know that she will ask you to define what you really mean and want by CRM. You will come off the canvas with a much clearer idea of what will suit your needs.
Jack Fraenkel, Managing Director, Motivatories

Microsoft Dynamics CRM Implementation & Optimisation

Complex projects delivered with confidence.

Their skills in implementing Microsoft Dynamics into Quantum Exchange were stretched to the limit. As a result of their efforts, I was able to merge two companies and two groups of people into one unified team and managed to do so in a tight time schedule.
Paul Gabrielides, Managing Director, Quantum Exchange

Opsis were brought into LPI to help the organisation transition from multiple CRMs to a single integrated Microsoft Dynamics CRM solution. Opsis were extremely professional throughout the process, demonstrating an excellent grasp of both business and technical issues.

Empowering teams—not overwhelming them.

Thank you Gill Walker for the amazing PL-200 technical training! Thank you so much for everything! You are an amazing trainer! It was a very nice experience!
Codruta Guler, Project Consultant, Aspira

I learned a lot of new stuff concerning model driven applications and Dataverse, since we work mainly with SharePoint as a back-end. But I have a feeling that is going to change in the near future.

CRM that people actually want to use.

Opsis has helped us to better understand campaigns and the sales process in CRM and we can now see where productivity can be improved across the business.
Kelly Hutchinson, General Manager, Australian Information Industry Association

The employee satisfaction has increased because the team are not creating reports as a separate activity. Lost customers are a thing of the past.

Gill has an innate ability to cut through the fog, and explain complex systems to newbies and experts in a clear and fascinating manner.

Sales, Marketing & Customer Engagement Optimisation

Less manual work. More selling. Better insights.

Repeat orders are easy too – our BDMs just copy the previous order with a couple of clicks. It saves me a day or two every week entering sales into MYOB.

We are now able to complete client proposals in an average of 30–40 minutes, a process that used to take anywhere up to 2 hours previously.
Wal Williams, Sales Manager, Ico
